This retrospective cohort study examined patients with active wet age-related macular degeneration (AMD) who underwent cataract surgery.
The study found no significant difference in best-corrected visual acuity (BCVA) between the two groups during the presurgery portion of the study. After cataract surgery, the surgical group had a significant improvement in BCVA compared with the nonsurgical group.
This study concludes that patients with stable disease may be candidates for cataract extraction. They probably will not have a worse outcome and, in fact, will have improved BCVA after surgery.
The authors expressed caution in adopting their findings for all wet AMD patients. Cataract extraction ought to be limited only to patients with stable disease—a safe strategy considering that outcomes after cataract surgery in patients with wet AMD are still debatable.

A study in Optometry & Vision Science finds that patients had a history of advanced AMD and age-related cataract and underwent cataract surgery had positive results. At 3 months postoperatively, best-corrected visual acuity and utility value using time trade-off method were compared prior to surgery.
“Usually, surgeons and patients were pessimistic about the outcomes of cataract surgery in patients with coexistent advanced macular degeneration, and the present study could provide valuable references for them as to whether to perform the surgery from the aspects of visual acuity, quality of life and health economics,” the researchers wrote.

The human lens is comprised largely of crystallin proteins assembled into a highly ordered, interactive macro-structure essential for lens transparency and refractive index. Any disruption of intra- or inter-protein interactions will alter this delicate structure, exposing hydrophobic surfaces, with consequent protein aggregation and cataract formation. Cataracts are the most common cause of blindness worldwide, affecting tens of millions of people1, and currently the only treatment is surgical removal of cataractous lenses.
Researchers at University of California San Diego have identified lanosterol as a key molecule in the prevention of cataract formation that points to a novel strategy for cataract prevention and non-surgical treatment. The abstract is freely available fromNature. If you have cataracts, you might want to purchase a full reprint while you can still read it.
Similar eye drops have been used to treat cataracts in Europe for many years.

Only an eye care professional can diagnose cataracts, but it may be time to schedule an eye exam if you notice any of these common signs:
- Blurry or fuzzy vision
- Trouble seeing at night
- Double vision (single objects appear as two)
- A glow or halo effect around lights
- Changes to color vision (colors are less vivid, maybe brownish)

Dr. Robert Abel, Ophthalmologist, was the guest on the People’s Pharmacy on Staurday, May 14, 2011. It was Show # 813, Preserving Your Vision.
Most of us take our vision for granted until it starts to give us trouble. Dry eyes can be a consequence of too much time in front of a screen. Are there other lifestyle factors putting us at risk for vision problems?
Cataracts, glaucoma and macular degeneration are major causes of vision loss. What can we do to prevent their development?
Guest: Robert Abel, Jr., MD, is an ophthalmologist with Delaware Ophthalmology Consultants. His books include The Eye Care Revolution and The DHA Story and most recently the novel Lethal Hindsight. His website is www.eyeadvisory.com
He gave excellent advice on Glaucoma, Macular Degeneration, eye nutrition and Cataracts.
The podcast of this program will be available the Monday after the broadcast date. Podcasts can be downloaded for free for six weeks after the date of broadcast. After that time has passed, digital downloads are available for $2.99. CDs may be purchased at any time after broadcast for $9.99.
